Routes are published by the person or the firm (their bio, the team page or a filing) and are revealed on a plan; data bought from a provider is never shown, and a route printed at a firm the person has since left is held back.

What these amounts and dates areEach commitment is counted once across the pension tape and the allocator graph. A commitment date prints only when the source printed one; otherwise the row carries the report date. A foundation’s 990-PF line is a holding at fair value, never a commitment. Rows without a fund on the venture graph are commitments to this manager.| Allocator | Type | Fund | Amount | Date | Source |
|---|---|---|---|---|---|
| Hillman Family Foundations | FOUNDATION | RA Capital Nexus Fund , L.P. | $3.9M fair value on the foundation's return | reported as of Dec 31, 2024 | Fact IRS Form 990 / 990-PF e-file returns |
